Alpha-N

Note that it is highly recommended to place an RPM bin (r table) on both hybrid_rpm_a and hybrid_rpm_m (3200 and 4800 RPM in the example) because the tables will look strange (and possibly steep) between these columns. The reason is the smooth, continuous change. The function that selects relevant table-lines blends smoothly from TPS to MAP as the RPM goes up from hybrid_rpm_a to hybrid_rpm_m.
Otherwise the TPS is highly nonlinear at low RPM, as an example, TPS=6% can result in 70% of the available power at 1000 RPM. Also note that any changes in the TPS sensor position will affect the VE table heavily in the alpha-n region.
Notes
- VE_learn currently works for speed-density only, not for Alpha-N
- make sure to adjust VE learning not to learn under hybrid_rpm_m (if using VE learning at all)
- MegaTune theoretically moves the dot according to kpa_tps_blend below hybrid_rpm_m (and according to high-resolution MAP above that RPM). However, be suspicious until you find it acting right.
